The ISL72813SEH is a radiation hardened, high-voltage, high-current, driver circuit fabricated using Intersil’s proprietary PR40 silicon-on-insulator process technology to mitigate single-event effects. This device integrates 32 driver circuits that feature high-voltage, common emitter, and open-collector outputs with a 42V breakdown voltage and a peak current rating of 600mA.

To further reduce solution size and increase system power density, the ISL72813SEH integrates a 5-bit to 32-channel decoder (plus enable pin) as well as level shifting circuitry to reference the output of the decoder to a negative voltage. This conveniently allows the user to select 1 of 32 available driver channels. The inputs to the decoder are TTL/CMOS compatible, allowing easy interface to CPUs, FPGAs, or μprocessors.

The ISL72813SEH operates across the military temperature range from -55°C to +125°C and is available in a 44 Ld hermetically sealed Ceramic Lead-Less Chip Carrier (CLCC) package.
